SPEAKING-TUBE.

SPECIFICATION forming part of Letters Patent No. 285,120, dated September 18, 1883,

Application filed February Q0, 1883. (No model.) I

To all whom it may concern-.-

Be it known that I, E. NEILsoN GAILLARD, a citizen of the United States, residing in the city, county, and State of New York, have inf vented a new and usef'ul Combined Gall-Bell and Speaking-Tube, of which the following is a specification.

My invention relates to a combination of a mouth-piece is drawn out in the same manner that a bell-pull is operated an alarm will be sounded to call the attention of the driver or other party whose attention is required, who can then be communicated with through the speaking-tube.

The mechanism of this invention is illustrated in the accompanying drawings, in which Figure lis alongitudinal sectional view, showing the speaking-tube, alarm-bell, and the mechanism for drawing back the Inoutl'I-piece and operating the hammer of the bell. Fig. 2 is a cross-section through line' e d, Fig. 1.

Similar letters referto similar parts throughout the different views.

X is the partition of a.cab or other vehicle, to which the combined speaking-tube and alarm is attached, the mouth-piece T projecting inside, andthe gong G is fastened upon the outside by means ofthe central tubular standard, M, provided with the flange I). The mouth-piece T has an extension, N, which slides inside the tube M. One end of the spring XV is attached inside the mouth-piece at g, and the other` end inside the extension of the tubular standard M at h, and by this spring IV the sliding mouth-piece is drawn up tothe partition X. Projecting through a slot in the tubular standard M is arranged the stud H in such a manner that it moves with the mouth-piece T when the latter is drawn away from the partition X, and is drawn back with it by the spring IV. The stud H is so adjusted in connection with the pivoted toe L and hammer B, which works on a pivot at K, that when the mouth-piece Tis pulled, the stud H draws the bell-hammer B against the spring Z and strikes the bell, and when the mouth-piece T is released the spring NV draws back the mouth-piece and its stud, the pivoted toe L allowing the stud H to pass by the end of the hammer B, and the spring Z presses the hammer back away from the bell. The eX- tension of the tubular standard at h is arranged for the attachment of a flexible or other continuation of the speakingtube,which may be of vsuch form and length as to best adapt it to the position of the driver.

By this description it will be seen that a very compact and effective arrangement of speakingtube and alarm is obtained by my invention, and that in use it is only necessary to use the mouth-piece of the speaking-tube as anordinary bell-pull is used, and thus strike `the alarm, after which the driver can be communicated with through the tube.

Vhile this invention is especially adapted for use in covered vehicles, it may be used in other K situations to which its construction adapts it. Having described my invention, I claiml. In combination with a speaking-tube, the reciprocating mouth-piece and connecting mechanism and a bell or resonator for giving alarm by drawing ont the mouth-piece, constructed and arranged as hereinbefore set forth. 2. The combination of the speaking-tube, the reciprocating mouth-piece T, the stud H, tripping-toe L, and hammer B, and reacting spring IV, forming the connection with the bell G, constructed and arranged as hereinbefore set forth.

In witness whereof I have hereunto subscribed my name and affixed my seal in the presence of two subscribing witnesses.
